We recently made a change to our search ranking algorithms, which you can read more about on the Official Google Blog: [googleblog.blogspot.com...]
According to our metrics, this update improves overall search quality. However, we are interested in hearing feedback from site owners and the community as we continue to refine our algorithms. If you know of a high quality site that has been negatively affected by this change, please bring it to our attention in this thread. Note that as this is an algorithmic change we are unable to make manual exceptions, but in cases of high quality content we can pass the examples along to the engineers who will look at them as they work on future iterations and improvements to the algorithm. So even if you don't see us responding, know that we're doing a lot of listening.
